F1.8 constant aperture super wide angle! Sigma 16-28mm full-frame lens coming?

Sigma has launched constant F1.8 zoom lenses in 2013 and 2016, 18-35mm F1.8 DC HSM|Art and 50-100mm F1.8 DC HSM|Art, even if these two lenses are only APS -C format, but it was still amazing at the time. After all, this type of super-large aperture zoom lens has a complex design, and not every lens manufacturer is willing to challenge it. Today, Sigma has already shifted its product focus from the former SLR system to a more advanced micro-single system. Due to the short rear focus distance of the micro-single system, the optical design flexibility is greater than that of the SLR lens, and it can design the previous SLR system. lens. Recently, Sigma has submitted a series of patents for E-mount constant large aperture ultra-wide-angle zoom lenses. Coincidentally, all three lenses have F1.8 large aperture. The three lenses are 15-24mm F1.8, 16-28mm F1.8 and 18-30mm F1.8 respectively. It is reported that the lens length may be 16cm, which is 3cm to 3cm longer than the current Sony FE 16-35mm F2.8 GM. About 4cm. Although there are three lenses declared by Sigma this time, from the perspective of market acceptance or competitors of the same level, it should be that the 16-28mm F1.8 has a greater chance of commercialization. Because even compared with Sony's original FE 16-35mm F2.8 GM, the Sigma 16-28mm F1.8 is already very bright in the amount of incoming light, and the 28mm telephoto end is also used relatively, there is no 15-24mm F1.8 24mm feels too wide-angle. As for the 18-30mm F1.8 wide-angle end specification, it is not too prominent. Of course, if this lens is packaged as a cine lens, it will be another matter. via: sonyalpharumors
